Scope

GB/T 10230.1-2019 is the English-translated version of 分接开关第1部分：性能要求和试验方法.

GB/T 10230.1-2019 is the Chinese standard "Tap-changers -- Part 1: Performance requirements and test methods".

Its scope clause reads: This part of GB/T 10230 specifies the terms and definitions of tap-changers, conditions of use, technical requirements for on-load tap-changers, on-load Technical requirements for the electric mechanism of the tap-changer, technical requirements for the non-excited tap-changer, technical requirements Brand, non-excitation tap-changer warning label and manufacturer's instruction manual.

This section applies to resistive and reactive on-load tap-changers, non-excitation tap-changers and their electric mechanisms. This section applies to tap changers immersed in mineral insulating oil in accordance with GB 2536.

If conditions are right, it can also be applied to gas Taps insulated or immersed in other insulating liquids. This section mainly applies to on-load tap-changers with arc contacts.

If conditions apply, it can also be applied to on-load tap-changers without arcs. (For example. electronic conversion). This section applies to all types of tap-changers for power transformers and distribution transformers and reactors.

This section does not apply to the tap changer for traction transformers and traction reactors, and the capacity tap changer for capacity transformers. Its clauses include terms and definitions.
